The formula for circumference is C = 2πr, where r is the radius of the circle. However, the radius is half the diameter, so the circumference could also be calculated using the formula C = πd, where d is the diameter of the circle. π is commonly shortened to 3.14.
If the diameter of the circle is 6 feet, an estimate of the circle's circumference is 6 times 3 feet or 18 feet.
Answer:
18 ft
Then, Owen only uses one piece of the 4 yard ropes.

A box has six sides.
Using the dimensions of the box:
2 sides are 5 x 7
2 sides are 7 x 3
2 sides are 5 x 3
Now calculate the total area:
2 x 5 x 7 = 70
2 x 7 x 3 = 42
2 x 5 x 3 = 30
Total area = 70 + 42 + 30 = 142 square inches.
